摘要:
卵黄囊是孕囊内非常重要的结构，在胚胎早期发育中发挥着造血、营养、生殖、代谢、免疫、排泄和内分泌等功能。卵黄囊容易受多种因素影响，在超声上表现为直径过大或过小、形态不规则、回声异常、钙化等，卵黄囊的形态改变和妊娠结局相关，形态异常易引起早期自然流产，卵黄囊直径过大和染色体异常密切相关，多篇文献报道卵黄囊和羊膜囊数目的非一致性，说明卵黄囊不能确定羊膜囊性。最新研究发现巨噬细胞来源于卵黄囊，参与免疫调节。卵黄囊和早产以及糖尿病的关系还在表面的推测上，缺乏大量临床数据及理论依据来进一步证实。
Abstract:
Abstract：The yolk sac is a very important structure in the gestational sac,which plays a role in hematopoiesis,nutrition,reproduction, metabolism,immunity,excretion and endocrine in the early development of the embryo.The yolk sac is easily affected by many factors, such as excessive or too small diameter,irregular shape,abnormal echo,calcification,etc.The morphological changes of the yolk sac are related to the pregnancy outcome,and the abnormal morphology is easy to cause early spontaneous abortion,the diameter of the yolk sac is too large and closely related to chromosomal abnormalities.Many reports have reported the inconsistency of the number of yolk sac and amniotic sac,indicating that the yolk sac cannot determine the cysticity of the amniotic membrane.The latest research found that macrophages are derived from the yolk sac and participate in immune regulation.The relationship between yolk sac and premature birth and diabetes is still further speculated on the surface,lacking a large amount of clinical data and theoretical basis to further confirm.
